According to research conducted on online retailers, informing customers when out-of-stock products become available again converts between 10% and 15% of requests into actual sales.
Have you run out of stock of one of your best-selling products? Are you awaiting supplies but fearful of losing customers? Allow them to put the out-of-stock item to a product waiting list and notify them via email when it becomes available in your e-commerce.
This prevents you from losing consumers and is the simplest approach to keep them loyal without allowing them to leave. You’ll see an increase in sales and client satisfaction.
